Conservative village office administrative percentageof total project cost less ABSN Admin %. Total projectcost = $180,300/village - (our admin percentage,(around 14%) Approx: $25,242) = $155,058 x 4% =$6,202.32 (this 4% village admin cost estimate is spreadacross all entities we work with for the course of thegrant for completing all energy efficiency measures).These are for cumulative, otherwise unaccounted timeexpense for village-based project support.
